Atomic Batteries: Energy from Radioactivity
Suhas Kumar
With alternate, sustainable, natural sources of energy being sought after, there is new interest in energy from radioactivity, including natural and waste radioactive materials. A…
Characterization of electronic structure of periodically strained graphene
Marjan Aslani, C. Michael Garner, Suhas Kumar +3
We induced periodic biaxial tensile strain in polycrystalline graphene by wrapping it over a substrate with repeating pillar-like structures with a periodicity of 600 nm. Using Ram…
Local Temperature Redistribution and Structural Transition During Joule-Heating-Driven Conductance Switching in VO2
Suhas Kumar, Matthew D. Pickett, John Paul Strachan +3
Joule-heating induced conductance-switching is studied in VO2, a Mott insulator. Complementary in-situ techniques including optical characterization, blackbody microscopy, scanning…
In-operando synchronous time-multiplexed O K-edge x-ray absorption spectromicroscopy of functioning tantalum oxide memristors
Suhas Kumar, Catherine E. Graves, John Paul Strachan +4
Memristors are receiving keen interest because of their potential varied applications and promising large-scale information storage capabilities. Tantalum oxide is a memristive mat…
